DEMOUNTABLE RIM.

Application led March 7, 1913, Serial No. 752,584. Renewed December?, 1914. Serial No. 875,185.

T0 allwhomz't may concern:

Be it known that I, JOSEPH A. ANcLaDA, a citizen of the United States, and a res1dent of New York city, borough of Brooklyn, 1n the county of Kings and State of New York, have invented certain new and useful Im# provements in Demountable Rims, of which the following is a specification.

This invention relates to demountable rims, particularly such as are used for vehicle tires. i

In the ordinary forms of demountable rims, great diiiculty has often been, experienced due to the binding action ofthe movable element, making it diiiicult to readily remove the rim from the wheel. Also digiticulty has often been experienced in obtaining a snug lit of the rim about the wheel at all points and thus considerable annoyance resulted due tothe wearing and rattling of the parts. In certain cases where attempt has been made to overcome these defects, re-v sort has been had to a plurality of adjustments which made it a tedious and laborious matter to mount the rim upon thev wheel and also iii many cases it has been found difficult to readily remove the rim when once mount: ed and clamped in position.

l The present invention has for its principal object to overcome these diiliculties and to this end, I provide a somewhat flexible resilient wedging member which is inserted between the rim and felly and which may, j

if desired, be actuated by a single actuating member to cause the successive portions of -the wedging member to wedge in between the rim and felly, so as to clamp` the rim to the wheel and also rigidly support the same in a radial direction at all-points about the circumference of the wheel. Also when the rim is to be removed, this single actuating member serves to unclanrp successive portions of the same wedging member and thus makes it easier to unclamp the rim from the wheel, as the resistance-offered to the release f' of the wedge is merely that of the individual portions of the length of the flexible wedging member, and thus the resistance'at any given instant during the releasing .operation is a fraction of the total resistance oered by the entire wedging member. Preferably, I make .this wedging member inthe form of a split ring of spring metal and the actuating member operates by drawing this ring circumfer- 'Mso as to unclamp the latter.

entially about the wheel. The ring may be normally either of slightly larger or slightly' smaller diameter than the felly. rlChus when it is first .inserted between therim and felly and pulled circumferentially from oneend, the farther end will be the first to be brought into firm engagement between the felly and rim, and as the pull is increased, successive portions of the wedge are brought into firm engagement until the entire length of the Wedge is in proper position and the rim is firmly clamped to the wheel. According to my preferred construction, the wedge in moving circumferentially about the felly is guided so as to receive alateral movement which results in the wedging action, and the same actuating mechanism which is used for actuating the -wedge into engagement is also of engagement with the felly band and rim In'suoh con-I struction, the successive unclamping of por? tions of the wedge is readily accomplished. In addition tothe advantages set forth above, the construction is inexpensive, light, etlicient, and not liable to get out of order.

Various further objects and advantages will more fully appear Ifrom the'4 detailed dey l scription and the features of novelty in construction and combination of parts will be particularly pointed out in the claims. i

The action corresponds to the tightening of espiing Wire about s wheel.

y in seme integree spond to the thickness of the band 11. Otherwise the construction is similar to the preferred form illustrated in Figs. 1 to e..

In Figs. 9 to 11, I have illustrated a clamping ring which is split to form a plurality of segments 50, 51, 52 and 53. rIhe slots 54 in the adjacent segments engaging the pins 55 are formed in opposite directions, so that when two adjacent segments are pulled toward each other by any desired means as for instance a lever 56 and link 57 (Fig. 9), the segments will clamp substantially as in the preferred construction. Vhen the segments are so clamped, a locking device consisting of a bar 58 having a. screw 59 extending therethrough at one end and a lug 60 extending therefrom at the opposite end, may engage in correspondingly formed apertures (31 and 62 at the ends of the adjacent segments, thus locking the latter in position.

In Fig. 12, I have illustrated another' modified form of actuating device for the clamp-- ing ring. This actuating device consists of a pinion 63 mounted upon a pin 64I suitably positioned on the felly or felly band. The pinion meshes with a rack 65 formed on one end of the clamping ring 1T. As the squared end of the pin 64 is engaged torotate the pinion, the pinion actuates the clamping ring and thus pulls it so as to cause the ring to wedge in by the engagement of the slots and peripherally disposed pins, as will be readily understood from the description of the other forms of the invention.

In the modification illustrated in Figs. 13 and 14, the rim 70 is formed with the inclined inner surfaces 71 and 72, the former f abutting an inclined shoulder 73 formed upon the band 74 attached to the felly. The band is also formed with inclined slots 75 at the side opposite tothe inclined shoulder 73. The clamping ring 76 has an outer inclined face 77 which is adapted to engage the inclined face 72 of the rim and is also provided on its inner surface with a plurality of inclined lugs 7 S which-register with the inclined slots 75 of the band.V When the ring is pulled circumferentially bythe action Aof the eccentric 23 on the stem 25, the ring will by reason of the engagement of the inclined'lugs and slots be moved inwardly to clamp the rim against the inclined shoulder 73.

In the form illustrated in Fig. 15, the rim 80 is formed with the inner inclined faces 81 and 82, the former of which engages the inclined shoulder 83 formed upon the band 84. The edgeof the band 84C opposite to the edge having the shoulder 83 is inclined inwardly and is'formed with a plurality of inclined slots 85 in which register inclined lugs 86 formed on the clamping ring 87. The latter is formedwith inner andouter inclined faces88 and 89 which engage respectively the inclined edge 84: of the band and the inclined face 82 of the rim. In this way, a double wedging action is obtained due to the two inclined surfaces of the ring which coperate' with the correspondinglyl inclined surfaces of the band and rim.

VIn the form illustrated in Fig. 16, the band 90 is formed with inclined slots 91 and the clamping` ring 92 is provided with the inwardly extending pins 93 registering with the slots 91. This form illustrates how the inclined slots and pins may be transposed upon the band and clamping ring as compared with'the construction illustrated in Fig. 1. Y

It will `thus be seen that I have provided a demountable rim which may be readily clamped and unclamped by a single actuating member, whereas the resistance offered during the clamping and unclamping action is not at any one time the total resistance of the wedge, but is the resistance of a portion of the wedge, as consecutive portions Aof the latter are brought into and out of engagement with the felly bandv and rim through the action of the single actuating member. the wedge fits the rim and felly band@ at all points inasmuch as the wedge consists of a split ring, the various portions of which may readily adapt themselves to any inequalitles which may exist 1n the run and felly band, and thus the rim is supported at all points about the wheel and any rattling and resulting wear and noise areflectually obviated. Moreover, the construction is light and inexpensive and is veryreadily and cheaply manufactured.
